IMPROVEMENT IN MOTIVE POWER.

Specification forming part of Letters Patent No. 41,406, dated January26, 18(14; antedated January 24, 1864.

Figure 1 is a top view of a sugar-mill em bodying my improvement.spective view ot' the same.

A repreeents the bed-plate, and B the topplate, which, being united byposts C, constitute the frame.

The rolls l 2 3, although of less than half the diameter or one fourthof the weight of those now commonly in use, are of equal speed andefficiency of working surface.

Fig. 2 is a per- The requisite speed of grindingsurface isusuallyobtained by the large size of the rolls. This object I attain moreefficiently and eco nomically by gearingup77 in manner following:Journaled vertically in the frame, at one side thereof, is a shaft, D,which rises above the frame sufficiently for the attachment of a sweepThe shalt D earriesa large masterwheel, E, armed with two sets of cogs,one set, F, being situated on its periphery, and the other set, G, onits concavty. The mas terwheel E meshes exterior-ly in the pinions I Iand I I I, of the rolls 2 and 3, and interiorly in the pinion I, oftheroll l.

I have found it desirable to give the pinions and the master-wheel arelative proportion of one to three. These proportions result in givingto the peripheries of the rolls a speed greater than is usually obtainedby the large diameter of the common rolls. Such arrangement, togetherwith the use of sufiioient animal power, of which there is not commonlyany lack, insures the efficiency and dispatch, which is of such primaryimportance in this connection.

It will be seen that every roll is driven equally and directly from themaster-wheel, instead of from the pinion of one roll to that of thenext, and so on through the series.

It will also be seen that the master-Wheelin respect to its interior aswell as its exterior cogs-meshes with the pinions I, I I, I I I, of therolls at points immediately in line with the work or place of greateststress of the cane on the peripheries of the rolls. This arrangementenables the construction of a mill of any given capacity at much lessthan the usual weight and cost, and of much greater compactness. It alsoinsures a greater freedom from strain and oblique bearing, andconsequently a more perfect transmission of the power. It also enablesthe rolls 2 and 3 to be placed so near together as to dispense wholly,or nearly so, with a return-plate.

I claim herein as new and of 1nyinvention The arrangement ofthedoublycogged master-wheel E, meshing with the disconnected pinions I, II, I I I, coincident with the lines of contact of aseries of crushing`or other rolls, l 2 3, the whole being combined and operating togetherin the manner and for the objects stated.

In testimony of which invention I hereunto set my hand.
